Application filed July 18,

This invention relates to non-evaporating oil tanks. The prime object of this invention is to provide an oil tank with attachments to a floating deck, that will reduce the evaporation of oil to a minimum.

Other objects of the invention eonsistlng of novel features of construction and arrangements of parts will become apparent, by reference .to the following specifications which describe the invention in connection with the accompanying drawings Figure 1 is a sectional view, taken near the center of the device, showing a vertical view.

Figure 2 is a detailed sectional view of the floating deck, showing a depending channel edge and. supporting base of a U-shaped bucket, together with a cover plate.

Figure 3 is a perspective view of the U- shaped bucket.

Figure 4 is a plan view of an angular-1y supporting base of the U-shap'ed buckets wit several pieces of the U-shaped buckets and the cover, in place.

Figure 5 is a perspective view of the cover plate for the U-shaped buckets.

By referring to the drawings, it will be seen that numeral 1, indicates the bottom of the tank, numeral 2 indicates the sides of the tank, and 3 indicates the floating deck. This floating deck 3, is provided with a depending channel edge 4.

By referring to Figure 2, it will beseen that I have provided a supporting base 5,

which is secured to the floating deck 3,by

means of belts or rivets. This su 'iporting base 5, is provided with an inturned upper end 7, which slidably supports the U-shapcd bucket 8. This U-shaped bucket S, is provided with a tightly fitting pin 9, having an end 10, fitting looselyin a slot 11 formed in the inturned upper end 7 ofthe supportingbase 5. It will be seenthat the lower end 12 of the U-shaped bucket 8, is formed so as to be parallel with'and to slidably engage the inner surface ,of sides 2, of the circular tank.

By referring to Figures 2 and 5, it will be seen that I have provided a cover plate 14, for the'U-shaped bucket 8. By referring to Figure 5, it will be seen that I have provided an upwardl formed oti'set on edge 15, of the cover plate 14. Indescribing-the construction of this device where reference has been made to the figure of the drawing, the single number has been used in reference 1924. serial No. 726,795.

to the U-shaped bucket 8, and the cover plate 14. As a matter of fact in the complete assembly of the device there is a plurality of U-sha ped buckets 8, and cover plates 14.

The U-shaped buckets 8, may have one edge 13, provided with an offset so that an opposite edge 33, of another U-shaped bucket 8. may slide under it, so that when the U- shapedbucket 8 is in position (see Fig. 2.) it

the inturncd upper end 7, of the su )porting base By means of the end 10, o the pin 9,'which functions in the slot 11, it will be seen'that U-shaped buckets 8, and connectiug parts are kept, regularly spaced all around the surface of the inturned upper end 7, of the supporting base 5.

'65 presents a perfectly flat surface to rest on- It will be noticed by referring to the draw- -loosely in the slot 11, will allow the U- shaped buckets 8, to slidably move upwardly and inwardly producing an angular movement on the inturned upper end 7,0f the supporting base 5, whenever the U shaped buckets 8 meet an-obstruction, such as a lapping joint of the tank plates, or a protrudingrivet head, After passing the obstruction or obstructions above mentioned the U- shaped buckets 8 automatically by their own gravity slide back into their position again, engaging the inner side of the sides 2, of the circular tank, thereby preventing evaporation.

The drawing will show that in constructing after the U-shaped buckets 8 have been put in place, as above described, the cover plates 14, which have an offset on edge 15, and curved end 16, are securely fastened to an upper end 17, of the U-shaped buckets 8, by means of a bolt 18, and rest slidablyon the lower end 37, of the U-shaped buckets t5. \Vhen the cover plate 14 is so attached it is so spaced that the curved end 16 en gages the side 2 of the circular tank thereby assisting in preventing the evaporation of oil and preventing the admission of rain.

As one edge of the cover plate 14, is provided with an upwardly formed offset 15, it will be seen that an opposite edge 35 of another cover plate 14: may slide under it, so that when the cover plate ll is in position it presents a perfectly flat surface to rest on the ends 17 and 37 of the U-shaped 'end 37 ot' the U-shaped buckets 8. the upper end 17 of the U-shaped bucket 8 will move inwardly a sutlicient distance to allow the curved end 16 of the cover plate 14:, to )ass' the ol'istruction. while the lower end 34 of the U-shaped bucket 8 may move inwardly a shorter distance, thereby reducing the unsealing of the tank to a minimum. After the curved end It; of the cover plate let has passed the obstruction the U-shaped bucket 8, by its own gravity will return to normal position engaging the sides 2 of the circular tank. and because of the tension against the upper end 17 of the U-shaped bucket 8. the curved end 16 of the cover plate 14: will be forced back into normal position, against the sides 2 of the circular tank.

'lwo pipe lines 19 and 20 lead into the circular tank. The sections of the pipes 19 and :20 may be joined together in any manner known to the art. One end of the line 19 is attached to the side 2 of the circular tank, and the other end is ri idly attached eas es rigidly supported at any desired distance below the floating deck 3, so that after the tank has secured a few inches of oil, the discharge of the incoming oil will always be beneath the surface of the oil within the tank. -thereby preventing any surface agitation which would tend to induce evaporation.

By referring to Figure 1, it will be seen that the floating deck 3 is provided with legs 21. and a man-hole '22; also truss cables 23. To the upper portion 524, of the sides 2. of the circular tank. are secured in any desirable manner, a plurality of centering cables 25. which are in turn attached to a central post 26. over which slides a collar 27, to which is attached the floating deck 3.

Having thus described my invention,

What. I claim is 1. In an oil tank, a floating deck of less diameter than the tank, means slidably interposed between the deck and the side of the tank. a cover plate over the slidable means and a pin firmly attached to the slidable means and loosely moving in an under support of the slidable means.

2. in an oil tank. a floating deck of less diameter than the diameter of the tank, U-shapcd buckets slidably interposed between the edge of the floating deck and the sides of the tank. a cover attached to the U-shaped buckets, pins firmly attached to the underside of the U-shaped buckets and loosely moving in slots in the angular support of the U-shaped buckets. a plurality of pipe lines having hinged joints one end of each secured to the sides of the tank the other end of one secured to the underside of the floating deck for drainage purposes: and the other end of another line rigidly secured to the underside of the floating deck toact as supply pipe to the tank.

In testimony whereof I ailix my signature.

FRANK ALBERT IDDINGS.
